Downregulated expression of miR-92a and miR-92b was observed in theca cells of PCOS women and gene target analysis confirmed that both of these miRNAs regulate the expression of GATA6, whose protein products regulate the activity of human CYP17 promoter which is involved in lipid metabolism (Lin et al., 2015). Here, CYP17A1 is linked to polycystic ovary syndrome.
